x = 5
Step-by-step explanation:
Here, we are interested in calculating the value of x.
We can obtain this from the given angle in the question.
Mathematically;
<CDE = <YDE + <CDY
Thus;
147 = 10x-3 + 21x-5
147 = 31x -8
31x = 8 + 147
31x = 155
x = 155/31
x = 5

Step-by-step explanation:
I assume you mean "if the ratio of 7 less than a number and 7 more than the number is 2".
Let x be the number.
Ratio is division.
(x-7)/(x+7)=2
Multiply by (x+7) on each side:
x-7=2(x+7) = 2x+14
Add 7 on each side
x=2x+21
Subtract 2
-x=21
x=-21
